Just looking at the stats in Google, which are sourced from our world in data.
There is indeed a good relative protection compared to the unvaccinated. However, Delta seems to be worse in the absolute by about 2x. At least for intensive care, not sure anyone studied death.
The other thing is that severe disease protection did decline as well in Israel. Pre booster they fell to 80%, instead of the previou 95-98%.
This doesn’t sound like much, but it amounts to only 5x relative protection, vs earlier 20-50x relative protection.
And since Delta is 2x worse in absolute for severe disease, you get only a 2.5x absolute reduction in severe disease for the same level of cases. Then, if cases go up by 2.5x the actual number of severe disease instances are equal.
